Prostop filters are specialized high quality neutral density filters. They are most used to create motion blur in long exposure shots and can help create these effects in water, clouds and other moving objects. This kits range is in densities from 3 to 10 stops. Prostops include a foam gasket which sits between the filter and the holder to help eliminate light leakage.

The 67mm filters are ideal for smaller consumer DSLR lenses and mirrorless cameras. This is a perfect entry level filter system for compact cameras.

Fits the Formatt-Hitech 67mm holder system, so a single filter is usable on multiple lenses. Also fits the Cokin A Series holder.

Made from the highest quality optical resin available, with an index of refraction nearly identical to the finest optical glass.

High scratch resistance, low material fatigue, and chamfered corners to resist breakage so the filters will provide years of service.

Made in the UK using the world's most advanced, computer-controlled filter manufacturing technologies.
